Cheetah 15K.3 FC Product Manual, Rev. D 7 3.4 Reliability • 1,200,000 hour MTBF • LSI circuitry • Balanced low mass rotary voice coil actuator • Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.) • Dithering 3.5 Unformatted and formatted capacities Formatted capacity depends on the spare reallocation sectors scheme selected, the number of data tracks per sparing zone, and the number of alternate sectors (LBAs) per sparing zone. The following table shows the standard OEM model capacity: ST373453FC ST336753FC ST318453FC Formatted 088BB998h (73.4 Gbytes) 0445DCCCh (36.7 Gbytes) 0222EE66h (18.4 Gbytes) Unformatted 96.4 GB 48.2 GB 24.1 GB Standard OEM models are formatted to 512 bytes per block. You can order other capacities by requesting a different sparing scheme and logical block size. Note. For 2 gigabit operation sector sizes must be divisible by 8. The sector size is selectable at format time. Users having the necessary equipment may modify the data block size before issuing a format command and obtain different formatted capacities than those listed. Cheetah 15K.3 FC drives use a zone sparing scheme. The drive is divided into frequency zones with a variable number of spares in each zone. 3.6 Programmable drive capacity Using the Mode Select command, the drive can change its capacity to something less than maximum. See the Mode Select (6) parameter list table in the Fibre Channel Interface Manual, part number 7767496. A value of zero in the Number of Blocks field indicates that the drive will not change the capacity it is currently formatted to have. A number other than zero and less than the maximum number of LBAs in the Number of Blocks field changes the total drive capacity to the value in the Number of Blocks field. A value greater than the maximum number of LBAs is rounded down to the maximum capacity. 3.7 Factory-installed accessories OEM standard drives are shipped with the Cheetah 15K.3 FC Installation Guide (part number 100148127). 3.8 Factory-installed options You may order the following items which are incorporated at the manufacturing facility during production or packaged before shipping.
